Returns an unmodifiable view of the specified map.

Usage

From source file:Main.java

/**
 * Creates an unmodifiable shallow copy of the given original {@link Map}. <p> While the copy returns an immutable
 * copy of the {@link Map} the content is not cloned in any way. Unless the content is immutable by itself the
 * result is not fully immutable. In the shallow copy all references are the same as in the original {@link Map}!
 * </p>/*  w  ww.j a  v a2 s  . c  o m*/
 *
 * @param original The {@link Map} to copy the elements fro.
 * @param <K>      The type of the key
 * @param <V>      The type of the value
 *
 * @return Returns an immutable (unmodifiable) copy of the original {@link Map} with all the elements added but not
 * cloned!
